Listing files from a directory

[abhi_madhani]

Hi friends,

 

I took this script from php.net that lists a name of file from a specified directory.

 

	$path = "./files/";
if ($handle = opendir($path)) 
{
# 
while (false !== ($file = readdir($handle)))
{
	if ($file != "." && $file != "..")
	{
		$thelist .= '<a href="'.$file.'">'.$file.'</a>';
	}
}
closedir($handle);
}

 

can someone please shed off some light as to how this line of code is processed, and what it means.

 

while (false !== ($file = readdir($handle)))

 

Regards,

Abhishek

bascially says 'do it til there are no more files'

Thanks,

 

I understood that it means that reads the list of files, till there are no more in that directory.

 

So what role does !== [not identical to] plays in the while loop.

this part carries an implicit value of TRUE as long as there are more files

  ($file = readdir($handle))

Once there are no more files, the implicit value is now FALSE

so the !==  is saying to the "WHILE' - when the implict value become FALSE stop looping 

 

Make sense?

Alternatively you could use scandir

[greatstar00]

logically, these 2 are the same

while (false !== ($file = readdir($handle)))

 

while ($file = readdir($handle))

why you wouldnt just use scandir() i dont know.

Thanks for all your help.

 

I am really grateful to you people.

 

I am using this code, as I found it on php.net, but sooner or later I will try scandir() function to list file.

 

Thanks again.

Although its probably better to code your own as you would learn a lot more
